MACHINE FOR APPLYING CREAM AND LIKE MATERIALS T BISCUITS AND THE LIKE.

Application filed September is, 1924. Serial No. 738,375.

This invention relates to machines of the kind in which material such as cream and the like is applied to biscuits and the like, automatically from a hopper with the aid of two endless travelling webs one whereof serves to support the biscuits or other articles whilst the other which surmounts the same serves as a shape and thickness determining controller for the coating to be applied.

The object of the present invention is to effect certain improvements more particularly directed to the securing of the requisite sequence of operations in a thoroughly reliable manner with little liability to interference on account of the sticky nature of the coating material employed, whereby it is possible to manufacture satisfactorily, with little attention, so called sandwich biscuits comprising a filling disposed between two plain biscuits, the result being continuous delivery of properly finished and squared up products.

To this end a machine according to the invention, comprises the various arrangements and combination of parts hereinafter described with reference to the accompanying drawings whereof Fig. 1 is a side elevation and Fig. 2 a plan, Figs. 3 and 1 being end elevations looking at Fig. 1 from the left and right hand side respectively. Figs. 1 and 1 are underside views of a detail of Fig. 1. Fig. is a longitudinal section and Fig. (3 a cross section of the machine. Fig. 7 is a semidiagrammatic elevation of the belts of the machine and Fig. 8 is a sectional plan of the lower part of the machine. Fig. l) is a plan to a larger scale of a portion of the lower belt of Fig. 7. Figs. 10, 11 and 12 are sections corresponding to the lines -10, 11-41, 12--12 Orri 9. Fig. 13 is a sectional view to a larger scale of a part of Fig. Fig. Ll is a sectional elevation to a larger scale of a part of Fig. 3. Fig. is a plan with parts removed corres tionding to Fig. 1'1 and Fig. 16 is a part sectional elevation at right angles to Fig. it. I

In this machine the biscuit blanks are received in succession upon an endless carrier belt 1 with which is associated a stencil belt 2 arranged as shown in Fig. 7. The carrier belt 1 as shown in Figs. 9 to 12 consists of two relatively thick but narrow lengths or runs 3 of leather or the like spaced apart and held at the proper distance one from the other by transverse metal ties 4t adapted to support a thinner mid-run 5 of suitable ma terial such as a silk belt which serves to directly receive the biscuit blanks and is in.- terrupted at intervals by pins 6 adapted to dislodge blanks from a guide container 7 (Figs. 1 and into which they are initially fed and which they descend by gravity, said pins'G being riveted to the ties 4;. If desired, canvas and like pads 8 may be sewn to the underside of the silk belt 5 substantially equal in thickness to the ties 4. The spaced runs 3 may be secured to the driving chains 9 by pins 10 that project laterally from certain of the chain links, certain other links having studs 11 adapted to cooperate with holes in the stencil belt 2 which is thus driven, such an arrangement ensuring register between the biscuit blanks and stencil perforations in the belt 2, through which the cream or the like passes, that is not attainable or easily attainable by independent positive driving of the belts. The belt 2 travels around a pair of upper rollers 12 and a pair of lower rollers 13 which latter are, as shown in Figs. (3 and 8 formed with annular grooves 1 1, to clear the studs 11 of the carrier belt 1 the chains 9 of which pass around a pair of sprocket wheels15 on the shaft 16 and another pair of sprocket wheels 17 on the shaft 18.

As the carrier belt 1 approaches the guide container 7 the mid-run 5 encounters means such as a spring finger 19 that serves to keep the belt down, said finger being if desired provided with a layer 20 of Wiping material to remove final traces of stickiness from the mid-run 5. The finger 19 is narrow enough to allow the pins 6 to pass to opposite sides thereof. 21 is a rotary brush associated with the underside of the lower run of the carrier belt adapted to brush the latter so that it is presented in a clear and satisfactory condition at the position where the biscuit blanks are supplied, that is to say at the guide container 7. A pivoted gravity member 22 which may have slight 1y serrated under surface as shown in either Fig. 1 or Fig. 1' may be arranged to bear upon and guide the blanks as they leave the container 7. The stencil belt 2 which is in direct contact with the coating material and hence more liable to cause trouble is adapted to be wiped on both sides preferably by passage between scraper screws a6 attached to the wall l3.

J screwthreader" p r tions ofpins 9 that gliltlfif prevent a stencilled biscuit being carried round by the stencil belt 2, stripper lingers l igs. 5 and 8 may employed 21 tending close to the latter at or near t position where the advancing edge oi t coated biscuit should ordinarily leave stencil belt. ie filling material is con tained in a vertical hopper provided with a forcing do vn screw 1 arrangement or p idele 82, and with a rotary cit oli plate or hit and miss device 33 to which linked through an arm 3% a pull and push rod handles 36 being provided whereby such cevice can be instantly manipulated from an y one of a number oi points should any derangement, be observed. The screw 32 is driven fromthc shall:- 18 through chain and. sprocket gear 37 and bevel wheels 38.

In order thatit may be possible to control the thickness of the material deposited from the hopper, the carrier belt 1 is supported by a table 39 that is carried upon crankrods l0 or the like capable of being minutely adjusted through screws 11.

The biscuit blanks that complete the sandwich are automatically supplied from a storage receptacle 42, which like the container, 7 consists of a hopper or tube having an inner false w; ll such as shown in l i 13 *apablc of adjustment to suit diltere'nt sized biscuits as by means of nuts-fi l held against axial movement but rotatable by nilled discs l5 andco-acting with At bottom of the receptacle it) ue 1 i l and 15, is provided to take one b cuit at a time. ,The bis: iit is carried or dis placed by the slide ll into an opening 49 wherein the :lormed in a stationary plat slide l7 operates, which opening by men of apair of shutters 50, forms a the tempo ary holding oi the biscii ol nlc. At the proper time ,the recess is opened at the bottom and the biscuit falls on to the coated biscuit which is carried forward b the carrier belt.

Tl e release of the biscuit is etlected simultaneously at opposite e p is so that it tells evenly, a convenient method of so ensuring this result bei to mount the shutters 50in guides 5i tr guise for the main slide l7 ind to actuate stencil belt the shutters from the slide l? by a cam and pin arrangement, comprising for example the pins 52- upon the shutters passing through ii slots 53 in the plate ll) and entering koorcs 5 lin. the underside of the slide 4-7, the shape or the grooves a l bein clearly ll\"!\i'il in Fig. l5 where the slice is in an intermediate position. lVhen :lully retracted in the direction of the arrow, the pins 52 will have progressed along the pen tions oi the groove 54 inclined to the direc tion of trave: when the shutters will be entirely withdrawn. leaving the opening perfectly free, Whereas complete advancement of the slide ll in the opposite dir tion will com ersely cause the pins to enter the portions ol the grooves parallel to the line of travel H1011 the shutters will be e:-:-- tended l'i ther into the opening l-S. is an adjusmble stop for varying the ellective size of the opening '3 in the plate ll).

Briefly the operation oi the machine is as lollowsz The container '4' number is hand filled with a of bottom biscuit blanlcs and the storage r ceptacle sin'iilarly lilled with a numb-r of top biscuit,blanks, the hopper 31 being tilled with the cream that is'to complete the sandwich.

As soon as the shaft 16 is rotated by its spr iclict wheel 2 the carrier c I to travel in doing which the 11, produce a synchronous travel ol the The biscuit blanlts from the container 7 drop successirely into place upon the carrier belt 1 and l i tcr with the openings in the stencil lJtll so that when the outlet to the hopper -Jl reached the rei T" c. U.s 1.1. .n n.

quired quantity of cream is deposited thereon. As each creamed bottom blank reaches the aperture of the stationary plate 49 associated. with the receptacle 42 the shut- 50 which have erstwhile supported a top biscuit blank dislodged from the re ceptacle 42 are actuated to liberate the blank which then falls upon the creamed blank and is ready to be acted upon by the press ing roller 67 which is temporarily caused to bear upon it. From this point the sandwich biscuits are advanced until the strippers 68 are encountered when the biscuits are transferred to the conveyorQGO and the parts simultaneous y squar' d about one edge ii necessary.
